--Merr., EPFP 3 (1923) 378. India to Peninsular Malaysia and tropical
Australia. LUZON: Zambales. Open sandy places near the sea. “The
distribution is not yet clear, as H. brevifolium has not been recognized
as a species separate from H. strigosum by many authors. It seems to be
most common in the Philippines, where the greatest number of herbarium
specimens comes from, but there also collections from N India. Whether
there is really a gap between this area and the Philippines seems
doubtful” (Riedl 1997). Photos
